Another bug using RH7.0 version of g++...

Hhmmm, RH7.0 should never ship with an "experimental" compiler. If after
a stabilzation period the gcc maintainers still don't consider the compiler
stable (even with all stabilizing features added) it should not have been
put on an "official" distribution. The problem is that I as application
provider must now support this "exprimental" compiler (which means introducing
all kind of work arounds in the source and/or an overall lower optimization
level). Or should I tell all my users to who installed RH7.0 to first install
gcc 2.95.2 before compiling my app?

Anyway, as I reported later yesterday on gcc-bugs, the bugs I found in RH 7.0's
version of gcc are still there in the current CVS version so the bug reports
belong on gcc-bugs. I hope somebody gets around fixing them.

Besides the compiler crashes I also noted numerical instabilities when
compiling with -O2 which cause my program to crash. With -O things are fine.

Cheers, Fons.
